Performative overwork is more and more common in the United States, and long hours have long been the norm in medicine. During residency, doctors have traditionally been asked to work for up to 100 hours per week. A rule in 2003 capped residents hours at 80 hours per week. Older docs claim this practice skimps on training, and might be worse for patients. A new study indicates that there is no discernible reduction in quality of care across a number of metrics. Maybe the good old days weren’t so great.
